Windows update keeps installing already installed update

I have about 10 -20 machines that the WSUS server keeps pushing the win2k sp4
rollup1 update to (KB891861). Event viewer says the push was successful, yet
it wants to push again, and again... The users are all complaining that there
print spooler keeps crashing at the same time. The spooler is the issue I
really need to get fixed; I have changed the status on the update in the WSUS
console to not approved from install. Below is some event viewer logs from 1
of the PC's affected. The only thing I have noticed is that the “UpdateID�
when it say's its complete is normal, and the one when it wants to push is
all 0's, is this normal??? Thank you in advance for any help anyone may have.
